Disagree that that's the case.
When DCB were seeking a replacement for Daly, they did what they'd done for practically every managerial appointment at every age level for both codes over the last 10 years - formed a sub-committee to recommend somebody. I think it goes without saying that this process got its managerial appointments right far more often than it got it wrong over that period. This group came up with the then U21 manager Shay Boland. He was the provisional choice but was blackballed by the then playing panel. To boot, they indicated that they didn't want ANY native Dub managing the team because they wanted somebody that had played for/managed an All-Ireland winning team. Constrained by those limitation of having to find a culchie with a Celtic cross who was willing to do the travelling, the fact that the passing weeks had seen other potential candidates commit elsewhere and I've no doubt with their noses a little out of joint over the rebuff of their choice and the process which selected him, Cunningham was hired of what was available. I don't believe there was any standout alternative available. Given their intervention in the process, I believe there was (and remains) a definite element at County Board level of "you've made your bed, you can lie in it" and it's why there isn't much appetite to entertain the gripes of departing players. Because of that, I'd give odds of 100/1 on any intervention by the County Board before the end of the season.
Saying all that, and notwithstanding the other issues with Dublin hurling that his departure wouldn't fix, at present I see no justification for extending GC's reign beyond the end of this Championship. Only a Leinster Title or AI semi-final appearance this year should alter that stance IMO and I can't see either being achieved. We'd then be in a position to move forward and I hope that among the many lessons to be learnt from this episode is that with player power, just like any other power, comes great responsibility.
